CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 314,094, dated March 17, 1885.

Application filed November 22, 1884. (No model.)

To @ZZ whom, it may concern.-

Beit known that I, GEORGE W. WILSON, a citizen of the United States, residing at Murdock, in the county of Douglas, in the State of Illinois, have invented a new, useful, and important Improvement in Gultivators, of which the following description will be sufficient in law.

My invention relates to the adjustability Of the working parts.

In the drawings, Figure l is a side elevation of a combined cultivator and harrow with the front wheel removed. Fig. 2 is a plan view ofthe same; Fig. 3, a detail view ot' the clamp for adjustment of thc barrow-teeth;v

Eig. 4, a modification Ot' the barrow-teeth and clamp. V

The axle A is arched orbOw-shaped for its middle portion. The draft-pole Bis attached to the top of' the arch C, and has proper braces, a, extending to each side of the arch, where they are fastened .to the axle. The Object of the arch is to gain two nprights, D, (only one upright being shown in the drawings,) for securing by clamps b the two wings E F of the cultivator.Y Similar clamps, c, secure to the axle upon cach side ot' the arch a bifurcated or Y-shaped arm, M, for holding the barrow-teeth. The outward portions d of this arm are bent downward to admit ot' vertical adjustment `of the harrow-teeth G. These teeth are arranged in sets, there being two sets On each side of the arch, and the distance between each set is lengthened and shortened by an adjusting-lever, H. Each set of harrowteeth is adjustedl upon its supporting-arm by means of an Ordinary screwclamp, N, of clevis shape, held fast in any position by tightening-nuts s s. The harrowteeth,'instead of being curved, as in Fig. 1, may be straight and dat, as in Fig. 4. Inthe llatter case, by turning the vertical teeth sidewise or at an angle, the furrows may be widened. A fiat tooth is sharpened at the top, and the edge made is inserted into a groove under its supporting-bar. A tightening-nut then holds the tooth in place when set at any angle.

Vthont further explanation it is obvious that a quick adjustment of the cultivatorwings and the harrow-teeth is a principal feature in this invention.

Among others the` following advantages will result from this construction of a cultivator and harrow: It will plow very close to young corn without disturbing the roots. It is very effectual in destroying young weeds. It is an excellent pulverizer ofthe soil, doing the work of harrow and cultivator at one Operation. It will make a gradual sloping ridge from either side to the middle ofthe row, working all the ground between the rows. It is an excellent farming implement for working cane and broom-corn.

I am aware that an arched axle is well known in the art, and that harrowing-teeth have been made to follow Scrapers. In my device I deein it important that the harrow be hung upon the horizontal arm of the axle to give free vertical play, and that the Scrapers be hung upon the vertical arms to allow horizontal movement. l

What I claim is Y ln a wheel*cultivat-Or, the combination', with the arched axle, ofthe bifurcated frames M, secured to the horizontal arms of such axle,

and having cross-bars and knives or teeth G, v

the Scrapers E F in front of said knives and secured by branched arms to the vertical arms of theaxle, and the adjusting-bar H, substantially as shown and described.

In testimony whereof I hereunto set my hand, in presence of two. attesting witnesses, this 8th day of November, A. D. 1884.

GEORGE XV. VILSON.
